People who adhere to homosexual relationships claim that they were born that way and cannot help themselves. Scientists differ on this issue. However, many scientists agree on something: no more than 5% of all people are true homosexuals and bisexuals. Entering a same-sex relationship for the sake of curiosity, for career advancement, is called debauchery.

Step 1
The genetic hypothesis of homosexuality
To confirm this hypothesis, facts are presented about the presence of the gay gene on the Xq28 chromosome (i.e., the homosexuality gene is not located on the sex chromosome). Many scientists argue the opposite - they become homosexuals in the process of life under the influence of socio-psychological factors. To confirm this theory, numerous studies have been carried out with identical twins, which have the same set of genes. The studies were carried out in the USA by Professor S. L. Hersherger (1997), in Australia at the University of Queensland by a group of scientists: J. Bailey, P. Dunne and N. G. Martin (2000) et al. If homosexuality was strictly programmed, then both twins would adhere to homosexual orientation 100% of the time. However, after conducting research, it turned out that both twins adhered to a homosexual orientation only 30-40% of cases. Genes don't program our behavior. A person himself can follow or resist genetic inclinations, develop them (even with homoerotic fantasies) or suppress them.
Step 2
Physiological hypothesis of homosexuality
In humans, the hypothalamus is responsible for the sexual sphere. More precisely, according to Allen and Gorsky, it is the INAH3 hypothalamus region that is responsible for sexual orientation. Neuroscientist Simon LeVay (who was himself gay) studied the hypothalamic region INAH3 in 1991. By measuring these areas in deceased heterosexuals and homosexuals, he found that this area is smaller in homosexuals than in heterosexuals. It was concluded that heterosexual men have 2-3 times larger INAH3 sizes than women and homosexual men. The structure of the brain is laid in the early stages of embryonic development. Based on this, LeVay concluded that homosexual tendencies are strictly programmed, and a person cannot change them in the course of life. However, this statement is refuted by the scientist Neil Whitehead (New Zealand, 2011), who studied identical twins developing in the same prenatal conditions. According to him, if one twin is homosexual, then the chance that the second twin will be the same is 11% for men and 14% for women.
Step 3
The psychological hypothesis of homosexuality
Previously, scientists assumed that homosexuals grew up in families where there were no fathers or there were powerful mothers and passive fathers (I. Bieber, 1962), a kind and caring mother and a "loser" father (Veps, 1965), in families where the mother did not showed too much love and care, and the fathers were kind and considerate (Greenblatt, 1966). Subsequently, these and other psychological theories were not confirmed. A child raised in a dysfunctional family does not necessarily become a homosexual. A 2000 study in Australia on identical twins who grew up in the same family showed that only 30-40% of twins had the same orientation. If homosexuality was a consequence of the influence of parents on children, then in 100% of cases, twins would have the same sexual orientation. Most likely, the decisive factor was the unique events in the life of one of the twins (sexual abuse) and the child's reaction to these negative events.
